How to stop mail coming to rental property in my name

[Brad E.]

Hello everyone - I recently purchased a duplex with inherited tenants in one side.  The other side is open.

I have checked the mailbox for the open side several times and see that I am getting mail addressed to my name in that mail box.

I have written "not at this address" on the mail and put it back in the box for the mail person to pickup but the mail continues to come.

I am trying to play the role of 'property manager' instead of 'owner' to the tenants, per recommendations from several sources.  Getting mail at this address in my name is not helping with this goal.

Does anybody know how I can stop mail from going to this address addressed to my name?
